Have 65111 motor with flier 400a esc 12s, do you need vesc? Stoping after just few seconds
Probably settings in the esc, there used to be some (fossilic) windows software to configure the flier esc through a usb to serial dongle. I also remember that there were differen FW versions for planes and boats. I used a flier for my forst efoil build in 2019/2020, almost no one in this forum uses them anymore. There a better alternatives now a days. I’d go vesc.
